We are the UK's aviation and aerospace regulator and recognised as a world leader in its field. Our activities are diverse, enabling the aviation industry to meet the highest safety standards, and we pride ourselves on our ability to adapt to the constantly evolving aviation environment.
The Role
We are looking for an experienced hands-on Technical Architect or Systems design focused Principal Engineer to provide technical leadership across a portfolio of digital services.
This is a role that combines architecture, engineering, and delivery. You will work closely with software engineering teams, product managers, security specialists, and operational teams to design secure, reliable, and maintainable services that support the CAA's regulatory responsibilities.
You will help shape technical direction across our Next.js, .NET and Azure estate whilst remaining actively involved in delivery. The role will be approximately 70% architecture, design, and technical leadership and 30% hands-on engineering, although this will vary depending on delivery priorities and the complexity of the work.
Core Accountabilities
Technical architecture and leadership
Define and maintain architecture principles, standards, and patterns across multiple CAA digital services.
Produce solution designs and technical guidance that support secure, accessible, resilient, and supportable services.
Work with Engineering leads, Product, and delivery teams to identify technical risks, dependencies, and opportunities early, balancing business priorities, technical debt, security requirements and operational needs to develop a pragmatic technical roadmap.
Hands-on technical delivery
Lead technical and architecture spikes and proof of concepts where complex or high-risk decisions require validation. Support hands on prototyping of novel technical solutions to validate approaches before rollout.
Review solution designs, code, and technical approaches to improve consistency and quality across teams, and work alongside developers to resolve complex engineering problems.
Promote automation, modern engineering practices, and appropriate use of AI-assisted tooling within agreed CAA security, information management, and governance controls.
Working across teams
Work with product, engineering, architecture, security, data, and operational teams to translate business requirements into elegant, scalable technical solutions. Communicate decisions, risks, and trade-offs clearly to technical and non-technical colleagues.
Coach and mentor software engineers, helping develop software architecture, system design, and engineering capability across teams. Help engineers to grow and solve engineering blockers.
About You
5+ years of experience designing and delivering enterprise level cloud-based web applications and services, gained as a hands-on Technical Architect, Principal Engineer, Lead Engineer or in a similar senior technical role.
Able to communicate complex technical issues clearly through concise documentation, diagrams, and constructive conversations with technical and non-technical colleagues.
Technical skills and experience:
Experience with React, Next.js including server-side rendering and web performance.
Experience designing and building APIs, integrations and backend services using C# and .NET. Experience of messaging and event-driven patterns would be beneficial.
Hands on Azure experience, including application hosting, security, monitoring, networking, integration and platform services such as App Service, Functions, Azure SQL, Key Vault, API Management and Service Bus.
Working on software designs and solution architecture to agreed standards.
Able to make and explain architecture decisions based on business value, risk, security, maintainability, and operational needs, rather than pursuing an idealised technical solution.
Experience with CI/CD, automated testing, observability, application security, accessibility, and the operation of live services.
Desirable experience
Experienced working in a regulated, public-sector, or safety-critical environment.
Experienced modernising or replacing legacy applications whilst continuing to support live services.
Experienced designing solutions that use AI, automation, or intelligent services appropriately and securely.
Relevant Microsoft Azure certifications.

We will be moving to a new local home, up to a 15-mile radius of Aviation House, to minimise disruption for our valued colleagues and customers.
We are now working with colleagues and visitors to understand what we need in our new office, before we start our property search. We will sell Aviation House and land, vacate the site and move to new premises, but we do not expect to move before 2028
